Noncontrolling Interest [Abstract]
Stockholders' Equity and Noncontrolling Interests	10. STOCKHOLDERS’ EQUITY AND NONCONTROLLING INTERESTS QGT owns 51.0% of the outstanding shares of Cinos, a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea and, through a 60.0% interest in Cinos China. QGT is obligated to purchase shares held by two other shareholders of Cinos Co., Ltd. representing a combined 35.0% interest. QGT accounted for this unconditional obligation as an assumed liability and derecognized the 35% noncontrolling interest in Cinos China, which brings its controlling interest up to 86%. The carrying value of the remaining 14.0% interest held by others in Cinos and the 40.0% interest in Cinos China are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. The fair values of the noncontrolling interests were estimated based on the values of Cinos and Cinos China on a 100.0% basis. The values were calculated based on the pro-rata portion of total forecasted QGT earnings before interest expense, taxes, depreciation and amortization ("EBITDA") contributed by each entity. Management indicated that each entity's pro-rata portion of EBITDA was reasonably reflective of each entity's invested capital value at the acquisition date. The Company is obligated to purchase common stock owned by a Cinos shareholder at a fixed price per share, while the purchase price per share for the other shareholder is the greater of the then fair value of the common stock and the fixed price per share (floor). The Company has a firm obligation to purchase the shares and a call option, while the two shareholders have a put option. Accordingly, the fair value of the obligation as of September 27, 2019 of $8.5 million has been recorded as a non-current liability in the accompanying Condensed Consolidated Balance Sheets and represents a Level 3 measurement as discussed in Note 1 of the Company’s Condensed Consolidated Financial Statements. The agreement with Cinos allows for the purchase obligation to become due at various times through December 2022.
